Well according to last week's USA Today & all the performance mags I've read, the 2011 6.4 should be putting out 480 hp. Even the web site www.ontariostreetcar.com says the same thing. Strange though, no extractors (vents) on the lower front fenders. Guess that modification will come later. Overall from what I've seen the 2011 doesn't look that much different from its predecessors, oh well.
